I've been doing trials to install devstack+ovn pver the past week 15:32:40 <trinaths> ok 15:33:00 <Amir_m> 2. The trials were using CentOS7 and Ubuntu 16.04 LTS 15:33:17 <Amir_m> 3. Non of the trials succeeded :( 15:33:35 <trinaths> oh. Ubuntu 1604 must go well. 15:33:45 <trinaths> what is the issue you are seeing in ubuntu 1604 15:33:46 <trinaths> ? 15:33:47 <Amir_m> 4. On the other hand, installing Devstack is very smooth 15:34:15 <Amir_m> again: installing devstack alone isn't a problem 15:34:33 <trinaths> ok 15:35:13 <Amir_m> the problem is the same on centos and ubuntu, too many arguments to a function 15:35:32 <trinaths> can you post the error to John 15:35:33 <Amir_m> and the worlddump files doesn't tell alot 15:35:48 <trinaths> worlddump might not help on this 15:36:04 <Amir_m> currently I'm trying to install the stable Pike release with ovn 15:36:28 <trinaths> ok. 15:36:40 <trinaths> what is exact OVN/Devstack error you are facing ? 15:37:54 <Amir_m> error in OVS/datapath/linux/flow_netlink.c too many argument to function 'metadata_dst_alloc' 15:38:17 <trinaths> this ovs is from John ovn-sfc 3.0 repo ? 15:38:52 <Amir_m> no I'm trying to install devstack+ovn with the standard repos first to isolate problems 15:39:32 <trinaths> but when you try the same at your university lab you were successful with OVN+Devstack i guess 15:40:06 <Amir_m> it was once and never again 15:40:29 <trinaths> ok. 15:40:34 <Amir_m> My bit is that maybe they synchronized the queens release afterwards 15:40:46 <trinaths> ok. 15:40:53 <trinaths> give a try with Queens release . 15:40:56 <trinaths> then 15:40:56 <Amir_m> that is why I'm trying the pike 15:41:21 <Amir_m> all my trials were using queens 15:41:36 <trinaths> can you try Ocata rather than Pike. 15:41:36 <Amir_m> or in other words the latest 15:42:02 <Amir_m> after the trial with pike finish I will do 15:42:38 <trinaths> please shoot a mail with this error to John and opnfv-tech-discuss and ovs-discuss - brief the devstack environment. 15:42:43 <trinaths> ok 15:42:55 <Amir_m> sure 15:43:43 <trinaths> that way we may get some help from outside while we solve ourselves. 15:43:56 <trinaths> Ok. keep this on running this way. 15:43:58 <Amir_m> no problem 15:44:13 <trinaths> Lets hook to another task. 15:44:27 <trinaths> while both require devstack+ovn 15:45:00 <trinaths> you can get some knowledge on containers and VMs hybrid environment. 15:45:02 <Amir_m> which task do you mean? 15:45:21 <trinaths> this task doesn't require john ovn-sfc repo. 15:45:38 <Amir_m> ok 15:45:47 <trinaths> normal devstack+ovn can do this. 15:45:58 <Amir_m> do what? 15:46:33 <trinaths> which ever be achieved early 15:46:42 <trinaths> cn+vm hybrid support 15:46:47 <Amir_m> okay 15:47:01 <trinaths> #link http://docs.openvswitch.org/en/latest/howto/openstack-containers/ 15:47:40 <trinaths> #link https://github.com/shettyg/ovn-docker 15:48:51 <trinaths> apart from the task ovn-sfc, while in progress please go through, https://github.com/openvswitch/ovn-kubernetes/tree/master/vagrant 15:48:53 <trinaths> #link 15:49:10 <trinaths> #link https://github.com/openvswitch/ovn-kubernetes/tree/master/vagrant 15:49:39 <trinaths> with the above repo you can run ovn with k8s and understand networking with containers. 15:50:08 <trinaths> #link https://blog.russellbryant.net/category/docker/ 15:50:41 <trinaths> while john/ovs-discuss/opnfv-tech-discuss reply the errors, try Ovn with CN+VM 15:51:18 <Amir_m> you mean using vagrant 15:51:51 <trinaths> yes. its predefined env. where you have ovn+k8s env 15:52:03 <Amir_m> yes 15:52:37 <trinaths> it will be simple for you to understand container networking and OVN support for container with k8s coe. 15:52:57 <trinaths> I feel you will not have more hardships in this vagrant setup. 15:53:16 <trinaths> please give a try and let's see how it goes. 15:53:25 <Amir_m> sure 15:55:04 <trinaths> but for our cn+vm hybrid support with ovn, we use docker containers - https://github.com/shettyg/ovn-docker 15:55:34 <trinaths> we go for docker containers because installer projects adopt them easily. 15:56:02 <trinaths> #link http://docs.openvswitch.org/en/latest/howto/docker/ 15:56:43 <trinaths> #action 1.
